The pulmonary arteries and veins are an exception to the red/blue coloring rule. The pulmonary artery carries deoxygenated blood from the heart to the lungs, while the pulmonary veins return oxygenated blood from the lungs to the heart. Therefore, the pulmonary artery is colored blue, while the pulmonary vein is colored red.
